[f]or many diseases, when a person is given a blood test to see if he is infected, quite often the standard for infection is “presence of antibodies.”
This makes no sense at all. If vaccination produces those antibodies, it is heralded as protection. But if a diagnostic blood test reveals those same antibodies, it’s a signal of infection and disease.
Vaccine-produced antibodies=health. Antibodies naturally produced by the body=illness.
